What independent reviewers found

Sleep Foundation (Sep 2025): Testers found it very firm and bouncy, with excellent temperature neutrality, sturdy edges and barely any smell, but it passed a lot of motion and lacked cushioning for side sleepers. Page carries shop links and discount offers. Read it ↗
NapLab (Jun 2026): Measured 9/10, among the firmest they have tested, helped by coconut-fiber layers. Outstanding edge support and very fast response; cooling good but not great. Not enough pressure relief for most side sleepers, and the firm feel transfers more motion. NapLab discloses affiliate links. Read it ↗

Their testing, in our words. We haven’t tested these mattresses ourselves, and we don’t repeat their scores.
